Title: Wall panel connector and wall panel connecting method
Inventor: KAWAKAMI HIDETADA
IPC: E04B2/56
Filed: 1999-03-17
Abstract: PROBLEM TO BE SOLVED: To provide a wall panel connector which facilitates works for mounting a wall panel. SOLUTION: There is provided a wall panel connector which is comprised of pinching portions 32 which each pinch lip portions 27A, 27B superposed on each other from outside, and abutting portions 33 which each abut flanges 26A, 26B from inside of framework members 22A, 22B. By abutting the flanges 26A, 26B on the abutting portions 33, the positions of wall panels 17A, 17b to be connected can be automatically aligned with each other. Further by pinching the superposed lip portions 27A, 27B by the pinching portions 32, the frameworks 22A, 22B can be combined with each other without a gap therebetween while the positions of the wall panels, 17A, 17B to be connected being aligned with each other. Thus, steps or gaps are not formed between the wall panels 17A, 17B to be connected to each other, and works for mounting the wall panels 17 can be facilitated.

Title: Optical function element and optical module
Inventor: TODORI KENJI
IPC: G02F1/35
Filed: 1998-03-20
Abstract: PROBLEM TO BE SOLVED: To reduce the restrictions of wavelength at which a band end appears and to expand the width by which a function can be controlled by incorporating photonic crystal which has plural cycles in the traveling direction of light. SOLUTION: Grating type photonic crystal is basically used as the photonic crystal. A grating has periodic variation in refractive index when viewed at right angles to its grooves, so the photonic crystal is used. Namely, the photonic crystal having plural cycles in the traveling direction of light is formed by putting a couple of gratings 11 and 12 which differ in grating density opposite each other. Then light is transmitted between the gratings 11 and 12 which are put opposite each other. The photonic crystal has more band ends than single photonic crystal even if a subband gap is not formed, so wavelength at which the group speed and phase speed of light can be modulated can be increased.

Title: Emergency shutoff device for gas or the like
Inventor: YOKOUCHI MICHIYOSHI
IPC: F16K17/36
Filed: 1981-05-14
Abstract: PURPOSE:To shut the gas in emergency by such a construction that the secondary power is increased by the action of a metal globe when vibrations with an acceleration over a certain set value are applied. CONSTITUTION:When a steel ball 6 is hopped up, it will act as shown by the broken line 5. When, thereafter, the reset shaft 3 is lifted to add the force of a return spring 4 and the lower magnet 2 begins rising, an upper magnet 1 attracts it. The steel ball 6 has small power at this time, but the force applied to the lower magnet 2 is increased to a great extent. The ball 6 works as a trigger in this case. Because, in such a conditions, a wire fixture 14 is pulled up at the same time as the pull fitting 7 is raised, the wire 8 lifts the valve 6 to be pressed to the valve seat closely. Thus the gas flowing is stopped.

Title: Control of expansion ratio of foamed polyolefin
Inventor: CHIBA MINORU
IPC: B29C48/92
Filed: 1991-04-05
Abstract: PURPOSE:To control stably the expansion ratio of a foamed polyolefin according to the information on the color which changes with the expansion ratio. CONSTITUTION:A process for producing a foamed polyolefin by heating a composition comprising a polyolefin resin, a blowing agent and an antioxidant to a temperature equal to or higher than the decomposition temperature of the blowing agent, wherein the expansion ratio of the foamed polyolefin is controlled by detecting a change in the color of the composition resulting from the reaction of the blowing agent with the antioxidant. Thus, a foamed polyolefin is stably and continuously formed on a nonconductor core of, e.g. an optical fiber by controlling the expansion ratio according to the information on the color which changes with the expansion ratio and is used as a parameter instead of electrostatic capacity data measured with an electrostatic capacity measurement device placed in a cooling water tank.

Title: Power supply unit for driving circuit in common transmission line
Inventor: YAMANE HIDETO
IPC: H03K17/16
Filed: 1979-06-11
Abstract: PURPOSE:To prevent the noise applied at the application and disconnection of power supply to the common transmission line, by providing the means delaying the leading of the power supply voltage and quickening the trailing of it to hold the driving circuit in nonoperation state. CONSTITUTION:When the power supply switch in ON and the voltage A of the terminal 21 of the power supply unit reaches a value, the phototransistor TR26 is conductive, TR32 is inconductive and TR36 is conductive, and the voltage B at the power supply terminal 29 appears at the power supply terminal 19 as the voltage C, and the delay time until this voltage C appears is selected longer than the time when the point t1 of power supply application until the time point t2 where the peripheral circuit is stable for the operation. This is because the operation of the driving circuit is stable from the time point t4 when the voltage C exceeds V2. Further, when the power supply to the driving circuit is disconnected, the trailing of the power supply voltage A to the peripheral circuit (time point t7) is delayed more than the trailing of the power supply voltage C (time point t6). Thus, the production of noise to the common transmission line at the application and disconnection of the power supply of the driving circuit can be prevented.

Title: Toilet drainage system having water economizing function
Inventor: ROBAATO EMU IENZEN
IPC: E03D3/12
Filed: 1996-03-28
Abstract: PROBLEM TO BE SOLVED: To obtain improved double drainage systems, in which water is saved, by selecting long flushing or short flushing by selecting the rotation of one handle by a user and selectively driving one drain valve. SOLUTION: A handle 32 is rotated in the counterclockwise direction in a front view in the case of long flushing. The pawl nose section 43 of a cam 42 is brought into contact with the upper section of the second arm 36 of a driving lever 34 by the rotation. Consequently, the first arm 35 is lifted, and a flapper 64 is lifted from a valve seat 62. The movement of the arm 35 is controlled by a cutoff wall 90. On the other hand, the handle 32 is rotated in the clockwise direction in the case of short flushing. The pawl nose section 44 of the cam 42 is brought into contact with the lower section of the arm 36 by the rotation. Accordingly, the arm 35 is lifted in height lower than the case of long flushing.  Since the pawl nose section 43 is brought into contact with the upper section of the cutoff wall 90 and the excess revolution of the lever 34 is prevented at that time, the flapper 64 is not elevated from the valve seat 62 up to height in the case of long flushing.
